Abstract

A component includes an additively manufactured component with an internal passage; and an additively manufactured elongated member within the internal passage. A method of additively manufacturing a component including additively manufacturing a component with an internal passage; and additively manufacturing an elongated member within the internal passage concurrent with additively manufacturing the component.

Claims (21)

1 . A component, comprising:

an additively manufactured component with an internal passage; and

an additively manufactured an elongated member within the internal passage.

2 . The component as recited in claim 1 , wherein the additively manufactured component include a first flange, a second flange, and a conduit with the internal passage therebetween.

3 . The component as recited in claim 2 , wherein the conduit includes multiple bends.

4 . The component as recited in claim 2 , wherein the internal passage is non line of sight.

5 . The component as recited in claim 1 , wherein the additively manufactured elongated member extends along a centerline of the internal passage.

6 . The component as recited in claim 1 , wherein the additively manufactured elongated member extends along a centerline of the internal passage.

7 . The component as recited in claim 1 , wherein the internal passage defines an aspect ratio with a diameter to length of less that 1 : 4 .

8 . The component as recited in claim 1 , wherein a ratio between the internal passage internal diameter and the elongated member outer diameter is between 4.3:1 to 12.5:1.

9 . The component as recited in claim 1 , wherein the elongated member is between about 0.08 and 0.12 inches (˜2-3 mm) in diameter.

10 . The component as recited in claim 9 , wherein the internal passage is between about 0.5 and 1.0 inches (˜13-25 mm) in diameter.

11 . A method of additively manufacturing a component, comprising:

additively manufacturing a component with an internal passage; and

additively manufacturing an elongated member within the internal passage concurrent with additively manufacturing the component.

12 . The method as recited in claim 11 , further comprising cleaning the internal passage of conglomerated powder with the elongated member subsequent to completion of the additively manufacturing.

13 . The method as recited in claim 12 , further comprising removing the elongated member from within the internal passage subsequent to cleaning the internal passage.

14 . The method as recited in claim 13 , further comprising destructively removing the elongated member from within the internal passage subsequent to cleaning the internal passage.

15 . The method as recited in claim 13 , further comprising pulling the elongated member out of the internal passage subsequent to cleaning the internal passage.

16 . The method as recited in claim 11 , further comprising removing conglomerated powder from the external surfaces of the completed additively manufactured component.

17 . The method as recited in claim 16 , further comprising agitating the elongated member within the internal passage to remove clean the internal passage of conglomerated powder of the completed additively manufactured component.
